(BLACKSBURG, Va.) — One Virginia Tech student has been charged with murder and abduction in the killing of a 13-year-old girl, and a second student has been charged with helping him get rid of the girl’s body, police said Sunday.

Nicole Lovell, 13, of Blacksburg, Virginia — where Virginia Tech is located — went missing Jan. 27, the Blacksburg Police Department said. Her body was found on Saturday in Surry County, North Carolina, which is near the Virginia border, police said.

Virginia Tech student David Eisenhauer, 18, was charged Saturday with first-degree murder and one felony count of abduction, police said.

Virginia Tech student Natalie Keepers, 19, was also arrested and charged with one felony count of improper disposal of a dead body and one misdemeanor count of accessory after the fact in the commission of a felony, police announced Sunday.

The police said investigators looking into Nicole’s disappearance were led to Eisenhauer Friday night. Eisenhauer was first charged on Saturday with one felony count of abduction, police said. Then after Nicole’s body was found Saturday afternoon, he was also charged with murder, police said.

Keepers, of Laurel, Maryland, was arrested this morning, said police.

Eisenhauer and Nicole “were acquainted prior to her disappearance,” police said today. “Eisenhauer used this relationship to his advantage to abduct the 13-year-old and then kill her. Keepers helped Eisenhauer dispose of Nicole’s body.”

Eisenhauer and Keepers are both being held without bond at the Montgomery County Jail in Virginia, police said.

Nicole’s remains are at the Office of the Medical Examiner in Roanoke, Virginia, for autopsy and examination, police said.

The investigation into Nicole’s abduction and death are ongoing, police said Sunday.

According to the Baltimore Sun, Eisenhauer, who is from Columbia, Maryland, ran cross country at Virginia Tech. In 2015, he was named the Howard County, Maryalnd, indoor track Athlete of the Year, the Baltimore Sun reported.

Virginia Tech President Tim Sands said in an open letter Saturday, “Speaking on behalf of our community, let me say that our hearts go out to Nicole’s family and friends. As a father, as well as Virginia Tech’s president, I want to reassure you that our community is supportive and resilient.”
